It is very tricky; you also have to wonder if consideration also needs to be about the physical and mental ability to tour the parks like a non-DAS user (ability to jump from line to line).
I think limiting re-rides could get rather tricky... my understanding is the ADA is mostly about comparable access to things (like a ramp to a main entrance).
A non-Das user has the access to the back of the standby line until park close (VQ doesn't count), so I would think a DAS user needs the same access to their standby line equivalent (DAS return times).
This is actually IMHO one of the easiest "fixes" to the current DAS rules. Not allowing someone to tap into/redeem a LL while holding a DAS return time. I've argued for it many times before, but the summary of why I feel this way:
- A non-DAS user is not able to tap into/redeem a LL while waiting in a standby line, why should a DAS user?
- A DAS user can still buy and utilize G+ and ILL, just in a manner that is more similar to a non-DAS user
- This would in theory open up more LL slots and bring DAS users closer to non-DAS user touring.
- I have no problems with DAS users utilizing underused capacity while waiting for their return time (food, merch, shows, and walk on rides)
- I think there the practicality of everyone tapping into every standby line is technically possible, but would be a huge infrastructure change and thus not really worth it for Disney to implement
- People that tour like Splash are not breaking the rules/abusing the system and I don't blame them for touring that way (I would if I needed DAS). I think this is a Disney rule fault and Disney should close it because it further exacerbates the potential for DAS/non-DAS disparity.
